AppIicaticnOctcber 18, 1949, Serial No. 121,937 I (01. 18-47) 9 Claims.1

This invention relates to new and useful improvements in devices forforming soles on shoes and especially relates todevices for formingcomposition soles on shoes, and constitutes a continuation in part of myco-pending application, Serial No. 670,740, filed May 18, 1946, andentitled iShoe Last, now Patent No. 2,507,505.

A main object of this invention is to provide a simple, strong,efficient, and easily operable device whereby shoes may be mounted on auniversally mounted support so that in operating on them, for thepurpose of forming composition soles thereon, the support may be quicklyand easily swivelled around to present the shoe in a plurality ofpositions to the workman.

A further object is to provide a simple and efficient and relativelyeconomical device on which the-shoe can be easily and quickly mounted tohold it firmly in operative position and condition for the reception ofthe composition sole by pouring the composition material into a-moldwhich is formed around the shoe while on the support.

A still further object is to enable the mold to be easily and quicklyand accurately adjusted with respect to the shoe weld and upper and heldin this relation while the sole material is setting after being poured.

A still further object is toiprovide a simple and efilcient devicewhereby the mold and its related parts may be easily adapted andadjusted, with respect to any shoe no matter what its size, so that inthe matter of a few minutes, the same device may be adapted to firmlyand efliciently hold shoes of all sizes.

Yet another objectis to provide simple means whereby prior to forming acomposition sole on the shoe, the heel and inner sole may be separatelyand preliminarily treated to dispose them in the proper planar positionand relativegpositio'n.

Further and more specific objects, features, and advantages will moreclearly appear from a consideration of the detailed specificationhereinafter set forth especially when taken in connection with theaccompanying drawings which illustrate a present preferred form whichthe invention may assume and which form part of the specification.

In brief and general terms, the invention,

among other things, provides a supporting device for a shoe and thissupport includes a main frame orpedestal comprising outstretched spacedarms on a standard and preferably mounted so that the arms can be swungabout a vertical axis 2 from a base surface such as the floor or a worktable.

Pivoted within the outstretched arms of the main frame is a .secondaryframe pivoted on a horizontal axis and at one end adapted to support ashoe. On this end of the frame, an adjustable plate is mounted to partlysurround the sides of the shoe and provided with adjustable clamping andsupporting plates which hold the shoe upper and welt in position, aswell as to hold in placea molding strip of flexible material which runsaround the welt and the entire shoe, to form a recess into which fluidcomposition may be poured to set and harden therein to form a sole forthe shoe.

The adjustable plate on top of the, secondary frame has a three-pointsuspension, two of which is from the top of the secondary frame andrathird is from the top of an adjustable leg dependent from the base ofthe plate and associated with the other end of the secondary frame so asto enable the operator to adjust theplate around the sho to differingsizes of shoe. This leg has means thereon to limit its motion in onedirection with respect to the main pedestal so that one preferredposition for working on the shoe may be easily and quickly be achievedwithout any particular effort.

A further feature of the invention is to'provide a spring pressure meansto press on top of the shoe against the inner sole and the inner heelportion to assist in shaping them properly prior to the pouring of thesole composition and'to permit effective mounting of the shoe on thework support-and the proper shaping of itwhile on the support. Thispressure means can be quickly applied and released and the distributionof the pressure may be varied along the shoe to suit it to shoes ofdiiierent sizes and also diiferent distorted conditions of the upper andinner soles and heels.

The preferred forms of the invention herein are illustrated in thedrawings, of which: I

Fig. 1 is a side elevation, with certain parts in section, of theimproved machine;

Fig. 2 is a vertical transverse section taken on the line 2 z of Fig. 1;

Fig. 3 is a plan view of the machine;

Fig. 4 is a vertical section taken on th line 44 of Fig. 3; and,

Fig. 5 is a plan view of amodified form of .the machine in which themachine can-supportand handle a plurality of shoes to (be treated.

Referring now merely to the specific forms 0f the device illustrated inthe drawings and the construction thereof, it is seen in Figure 1, thatthere is a base member II] which can be screwed or bolted to a suitablesurface or platform ll. Projecting upward from the top of the base It isa hollow standard sleeve [2 and projecting into said sleeve 12 is a stubshaft or stem [3 having an enlarged upper portion l4 adapted to rest onthe top edge of the sleeve i2 and to be turned thereon at will. Thisstem [3 and the enlarged head 14, are integral with a frame memberhaving a horizontally extending beam i5 and upwardly extendingoppositely disposed arms l6 and IS on the ends of said beam i5.Extending vertically upward from these arms I5 and it, are adjustablerods or stems H and [1' having bearing sleeves l8 and [8 at theirrespective upper ends which have horizontal aligned axes.

Disposed to swing within the arms l6, l5, and rods H, H is another frameformed of vertical spaced elements l9 and 19' having at their upperends, horizontally outwardly extending stub shafts 29 and 20' projectinginto the bearing sleeves I8 and I8 respectively.

The lower portion of the frame of which the rods i9, is are sideelements, is formed of a cross beam 2! suitably connected at its ends tothe lower ends of the rods i9, i9. Along the upper edge of this crossbeam 2| is adjustably disposed a clamping member 22, which at its loweredge, engages the beam 2| and also clamps between its members an uprightrod or stem 23 the lower end of which is ball-shaped as at 24, to begripped by the clamping device 22. At its upper end, this stem 23 ispinned between the free ends of a U-shaped metal strap 25, theintermediate portion of which is riveted to the narrow end of the soleplate 25 of the shoe last, as seen in Figure l and a shoe last block 26which is more in detail shown and of the general form shown in myco-pending application, Serial No. 1

shoe having an upper 30 disposed over the last with its innersole 3|facing upwardly and the last is' adjusted to tightly grip it and bedisposed therewithin. The sole has a usual welt portion 32 as seen mostclearly in Figure 4. The clamping means 22 may be tightened by means ofusual screws or bolts 33 as shown.

With the frame formed by the rods l9 disposed in a vertical plane asshown in Figure 1, and with the shoe supported horizontally on top ofthe stem 23 with the shoe last tightly in place, it becomes necessary toprovide means around the welt 32 to form a mold for pouring compositionmaterial on top of the innersole 3|. To this end, I dispose a U-shapedplate in a plane substantially that of the welt and innersole of theshoe and this plate has a base portion 33' and spaced limbs 34 and 34'extending therefrom along the sides of the shoes as seen particularly inFigure 3. The limbs are respectively provided with elongate slots 35 and35' upward through which extend threaded stems 36 and 38 mounted on orconnected in any suitable manner to the upper ends of the elements [9and I9 and forming continuations thereof. The plate rests on shouldersformed on the elements I9 and I9 and is engaged on its upper side bywing nuts 31 and 31, to

hold it in this position. The base portion 33' of this plate is held inproper position by reason of the projection upwardly therethrough ofanother threaded stem 33 with nut 39 on the upper side of the plate, anda wing nut 40 on the lower side. At the top of the stem 38 is a yokeelement 41 with a cross pivot pin 42 therein to receive the forked end43 of a long lever 44, the other end of which has a slot therein toreceive a threaded stem 45, the bottom of which is provided with acollar 45 surrounding the threaded shaft 29 of the shoe last abovedescribed. The upper end of the stem 45 is provided with a wing nut 41so that the lever 44 can be adjusted upwardly 0r downwardly as may bedesired.

The lever 44 has a central elongate slot 48 therein to receive a thinbar 49 having a transversely disposed bottom edge 50. Along the bottomof the bar 49 are disposed springs 51 and 5| bearing against the bottomof the bar at their top and bearing respectively against a metal plate52 and the inner heel portion 53 of the shoe as shown in Figure 1.Underneath the metal plate 52, there is generally disposed a layer ofsoft rubber, such as sponge rubber 54. The bar 59 has an elongate slot55 therein, in which rides a pin 56 fixed in the lever 44 and extendingacross the elongate slot 48 therein. This pin allows the bar 49 to bemoved longitudinally with respect to the pivot point afforded by the pin55 and thus distribute the variations in pressure of the lever 44 on thesprings 5| and 5| as desired. The purpose of this spring arrangement isto so press on the inner sole 3| and the inner heel portion 53, thatthey may be pressed fiat and even before any attempt is made to pour ona liquid composition sole. The pressure of these springs may be left onthe parts thus under treatment for one or more hours after which, thelever pressure is released and the device is lifted out of the way forthe pouring of the material in the manner to be now described.

The threaded stem 38 is anchored at its bottom in a lug 51 on adependent leg 58. It is held in position thereon by means of nuts 59 and60, as shown in Figure 1. Between the nut 59 on top of the lug 57 andthe lug, there is disposed a slidable plate 6| slotted to be movedforward or backward and having a forward tapered face (52 to bear asdesired against the top of the toe portion of the upper of the shoe, soas to help support the shoe in proper position, and it may be adjustedlongitudinally to fit shoes of various sizes.

The dependent leg 53 has a bottom horizontally extending portion 63 thetop of which passes through a notch 6 1 (Figure 2), in the cross member2!. A threaded shaft 55 passes through a threaded bore in the crossmember 2i and is journalled in flanges 56 and 67 of the leg 58 and has ahand knob 58. The turning of the threaded shaft will move the leghorizontally to adjust it and the mold supporting plate 33' with respectto the shoe as is clear. The leg 58 along its bottom portion, isprovided with a slot 69 through which extends a bolt 70. This bolt, whentightened, is associated with straps H and I! fastened to the bottom ofthe cross member 2| and disposed on either side of the horizontalportion of the leg 58. This will permit the leg 58 to be adjusted, andthen this adjusted relation is fixed by tightening up on the bolt 70 tohold the leg and therefore, the plate 33' in proper relation for anygiven shoe. Along the bottom of the horizontal portion 63 of the leg 58,are disposed adjustable stop clamps 72. These clamps are adapted to abutan eccentric cam disc 13, which is adjustably disposed on top of the midportion of the "main :frame "I Svmi'dway between the limbs or legs I6and I6. Thus it will be seen that the secondary frame may be swungaround the horizontal axis of the stub shafts 20 to invert the shoe atwill and then can be moved back to the position shown in Figure 1, topresent the bottom of the shoe upwardly in a predetermined positiondetermined by the setting of the clamps 12 with respect to the disc 13.

With the mold-supporting plate shown in Figure 3, having a base portion33 adjustablein a horizontal plane with respect to the shoe, the innersole and welt are surrounded by one or more strips of flexible materialto form a wall surrounding the inner sole and heel thus resulting in arecess into which may be poured fluid composition to form a sole andheel when set. The limbs 34 and 34' of the plate 33 at the sides "of theshoe, are provided with lower adjustable plates 15 and with upperadjustable plates 16. These respective plates are slotted to be slippedin position and to embrace a bolt l1 passing through the limbs of theplate '33 and with wing nuts 18 above and below the limbs to hold theseplates in adjusted position. The lower plates 15 extend beneath thelower edge of the flexible strips to hold them in position and the upperplates I6 are adjusted to bear against the side of the strips to holdthem in proper relation with respect to the inner sole and welt. Thelower plates have four sides of different curvature so that these sidesmay be selectively used to be disposed with shoes of'different shapesand sizes at will. The tapered face 62 of the plate I 6| has connectedthereto in any suitable manner, an elastic band 85 which, as shownFigure 1, extends therefrom on each side of the shoe and passes aroundthe flexible strip '54 at the bottom thereof, where it is disposedaround the heel portion 53 of the shoe. This elastic connection permitsthis portion of the strip to be firmly held in place.

At the sides of the shoe elongated bearing plates 19 are provided andare supported on the inner ends of strips 80 adjustably disposed beneaththe limbs 34 and 34' of the mold supporting plate, and are held inposition by means of the wing nuts 31 and 31' previously mentioned.

In order to guide the lever 44 in its up and downward movement, there isconnected thereto a cross bar 8| which is connected thereto by means ofU-shaped straps 82 bolting the cross bar Bl to the underside of thelever 6%, as shown in Figure 2. The ends of this bar Eli are bored toreceive the upper ends of the threaded stems 36 and 36, so that as thelever is moved up and down, the cross bar will be guided on these stemsin a controlled movement. Wing nuts 32 limit the upward movement of thebar 81.

In Figure 5, is shown in a schematic manner, the mounting of a pair ofsuch formers on a single mounting, each one of which may be manipulatedto swing around a horizontal axis and both to be swung as a unit arounda central vertical axis.

In the operation of this simple and efficient device, it will be seenthat it will enable a shoe to be held in position to be worked on and tobe manipulated to present it with its sole portion down or up asdesired, by merely turning the secondary frame on its axis in the mainframe. In operating the device, the shoe is prepared by inserting thelast therein to fit tightly therein and the stemfrom thelast projectsdownwardly andiis clamped in. the manner described to clamping meansassociated with the ,cross :memher at the bottom of thesecondary .framemember. Thisv therefore, wvill present theshoe with its inner sole andWelt facing upwardly in a plane substantially flush with the upper endof the secondary frame and in a;plane substantially the same as the moldsupporting plate 33' which .is adjustab-ly mounted on the upper end ofthis secondary frame, through the intermediary of the dependent legwhich can be adjusted by means of the threaded shaft associated betweenthe cross member of the secondary frame and the lower horizontal portionof the dependent leg. This adjustment depends entirely upon the type andsize of the shoe .to be disposed at the top of the frame as must now beclear.

If the inner heel portion and the inner .sole portion are somewhat outof shape andnot disposed flat, it may be necessary to apply the lever 44to exert pressure on these portions through the intermediary of thesprings disposed under the lever in the manner heretofore described.This will permit these portions to be pressed out fiat for a suitablelength of time before the molding strips are applied around the innersole to pour the liquid .material into the mold chamber to form the soleand heel. After this suitable length of time, the lever 44 with itsassociated elements is raised and the mold supporting plate is adjustedto position with respect to the shoeinner sole and welt by turning thethreaded shaft :at the bottom- 01" the dependent leg and associated withthe cross member of the secondary frame. This will adjust the plate withrespect to the inner sole and welt and will permit the adjustableelements on said plate to be adjusted to support the mold strips aroundthe sole and welt and to bear against said strips to hold them inintimate contact with the inner sole and welt. This adjustment alsoapplies to the elongate strip bearing elements at the side of the shoe.After all these adjustments are made, it is then that the material toform the sole and heel are poured into the mold recess, which isallowedto set after which the shoe can be removed.

It is therefore, seen that I have provided a main frame rotatable aroundone axis with a secondary frame supported therein rotatable aroundanother axis at right angles to the first axis. The secondary framesupports a shoe with its sole presented in a plane substantially flushwith the end of the frame and at right angles thereto, and the secondaryframe also supports a mold-supporting plate atright angles to said endand in a plane substantially coincident with the plane of the sole andheel with means to adjust the mold-supporting plate with respect to thesides of the inner sole and the welt. Means are provided on themold-supporting-plate to support a mold strip around the welt and innersole and to press it into proper and inti-' mate contact with said innersole and welt to form a proper recess for pouring liquid material intosaid recess or mold to set.

It is apparent that the shoe in the operative position may be even morefirmly held by the forward movement of the plate 6!, with the forwardtapered face to bear against the outer toe portion of the shoe upper andthat the adjustability of this plate will adapt the contact of thistapered portion to shoes of various sizes without any particulardifficulty whatsoever.
